Python 2.7 small code snippet and regex required

Hi, I have a simple job that should take a good programmer only a few minutes. The code will be used in Zapier and must be working in order to be considered delivered/complete. Zapier uses Python 2.7 PART 1: The string is in one of the following formats (INPUT): 2 1 adult 2 adults 1 adult, 1 child 2 adults, 1 child 1 adult, 2 children 2 adults, 2 children 1 adult, 1 child, 1 infant 1 adult, 1 child, 2 infants 1 adult, 2 children, 1 infant 1 adult, 2 children, 2 infants 2 adults, 1 child, 1 infant 2 adults, 1 child, 2 infants 2 adults, 2 children, 1 infant 2 adults, 2 children, 2 infants The format of the result string needs to be in the following format (OUTPUT): 1,1,1 Examples: INPUT => OUTPUT 2 adults, 1 child, 1 infant => 2,1,1 2 adults, 2 children => 2,2,0 2 adults, 1 infant => 2,0,1 2 => 2,0,0 PART 2: I need 3 Python Regular Expressions to extract the OUTPUT from part 1: INPUT: 2,3,1 OUTPUT: Regex 1 => 2 Regex 2 => 3 Regex 3 => 1 Only bid if you can do both PART 1 and PART 2. I am looking for this to be done very quickly. Max budget is 5USD.
